Original INR18650-30Q 3000mAh 15A High Drain 30A Discharge Lithium-ion Battery Cell for Power Tools

The INR18650-30Q is a legendary 3000mAh high-drain rechargeable lithium-ion cell in the standard 18650 form factor. Designed specifically for applications with strict spatial limitations that demand both high energy density and powerful current output, the 30Q has established itself as an industry benchmark for performance and reliability.

Offering a massive 3000mAh nominal capacity alongside an impressive 15A continuous discharge rating (and up to 30A discharge with proper 80°C thermal management), the INR18650-30Q eliminates the traditional tradeoff between run-time and power delivery.

Whether you are designing compact high-power packs or sourcing reliable replacement cells, the INR18650-30Q is the optimal solution for space-constrained, high-drain hardware. As a professional supplier, we provide factory-direct wholesale supply and competitive distributor pricing for global pack manufacturers and OEMs.

• Unrivaled Energy-to-Power Ratio: Combines a full 3000mAh capacity with 15A continuous current, delivering maximum operating hours under high load without switching to larger 21700 form factors.
• 30A Thermal-Limit Capability: Capable of sustaining pulse and high-rate output up to 30A continuous when supported by an 80°C surface thermal cut-off system.
• Low Internal Resistance: AC impedance of ≤26 mΩ minimizes voltage sag under heavy loads and reduces heat build-up inside tightly enclosed battery compartments.
• Fast Recharging Support: Supports up to 4A rated fast charging, reaching full capacity in approx. 70 minutes for minimum operational downtime.
• Proven Cycle & Storage Stability: Retains high discharge capacity over extended cycle life under continuous 15A discharge testing. Over 80% capacity recovery after 30-day storage at elevated temperatures (60°C).
• Strict Manufacturing Quality Control: Cell-to-cell consistency makes the 30Q an industry-favorite choice for building balanced multi-cell series and parallel battery packs.

• Cordless Power Tools: High-torque drills, rotary hammers, saws, angle grinders, and lawn equipment requiring sustained 15A+ current.
• Commercial Smart Cleaners: High-power handheld vacuum cleaners, floor scrubbers, and automated robotic cleaners.
• Light Electric Mobility (LEVs): Compact e-bike packs, electric kick scooters, and personal transportation devices where enclosure space is strictly limited.
• Medical & Industrial Devices: Portable diagnostic equipment, motorized medical carts, and industrial field tools.
• Portable Energy Storage & Backup Systems: Lightweight outdoor power stations and high-output emergency UPS modules.

To prevent leakage, excessive heating, fire, or explosion hazards, adhere strictly to the following safety rules:

• Voltage & Charging Limits: Charge exclusively with a dedicated Li-ion charger set to 4.20V ± 0.05V cut-off. Never exceed the 4A fast charge current or connect cells directly to AC mains.
• Operating Range: Maintain operating voltage strictly between 2.50V and 4.25V. Do not discharge below 2.50V or attempt to recharge severely over-discharged cells.
• Mandatory BMS Integration: Cells must be integrated into battery packs equipped with a certified Battery Management System (BMS) featuring thermal protection, over-charge, over-discharge, and short-circuit protection.
• No Direct Soldering: Never apply a soldering iron directly to the cell terminals. Use proper spot-welding equipment with nickel strips to prevent thermal damage to internal separators.
• Handling Precautions: Do not short-circuit positive and negative terminals with conductive objects. Never crush, puncture, disassemble, drop, or expose cells to water, high temperatures, or open flames.
• Cell Mixing Prohibition: Do not mix new and used cells, or combine 30Q cells with different battery brands, capacities, or chemistries.
• Storage Protocol: Store cells at low ambient temperatures (below 20°C recommended) at ex-factory partial charge levels (~30% SOC). Refresh charge stored cells periodically to prevent deep self-discharge.
